Mr McDonald, a delivery driver, was exposed to asbestos dust when he regularly visited Battersea Power Station to pick up waste products in the 1950s. The defendant argued that Mr McDonald and his family could not receive compensation because he was not employed by the occupier of the site and because their primary work was not directly involved in the asbestos industry. The ruling in the family’s favour clarifies the law and gives greater protection to current and future victims of industrial diseases and accidents, said lawyers representing the family of McDonald, who died a week before the hearing.
